Rømer was employed by the French government: Louis XIV made him tutor for the Dauphin, and he also took part in the construction of the magnificent fountains at Versailles.

Rømer also developed one of the first temperature scales.

# In Touch-Starting from an attempt for cheaper fusion power using superconductivity, which was discovered by Onnes, with liquid gas provided by Louis-Paul Cailletet, who carried out experiments on a tower built by Gustave Eiffel, who also built the Statue of Liberty with its famous poem by the Jewish activist Emma Lazarus, helped by Oliphant, whose boss Elgin was the son of the man who stole the Elgin Marbles and sold them with the help of royal painter Thomas Lawrence, whose colleague Dr. Hunter had an assistant whose wife's lodger was Benjamin Franklin, who charted the Gulf Stream with a thermometer Fahrenheit borrowed from Ole Rømer, whose friend Picard surveyed Versailles and provided the water for the fountains and the royal gardens and all the trees that inspired Duhamel to write the book on gardening that was read by the architect William Chambers, who hired the Scottish stonemason Thomas Telford, whose idea for London Bridge was turned down by Thomas Young, whose light waves travel in ether, as do Hertz's electricity waves, with which Helmholtz prods a frog to disprove the vitalists, whose leader, Klages, analyzes handwriting so individual zip codes have to be capital letters to get your mail to a jungle village to keep you " In Touch ".

Poincaré went on to note that Rømer also had to assume that Jupiter's moons obey Newton's laws, including the law of gravitation, whereas it would be possible to reconcile a different speed of light with the same observations if we assumed some different ( probably more complicated ) laws of motion.

Over a period of several months, Jean Picard and Rømer observed about 140 eclipses of Jupiter's moon Io, while in Paris Giovanni Domenico Cassini observed the same eclipses.

Assume the Earth is in L, at the second quadrature with Jupiter ( i. e. ALB is 90 °), and Io emerges from D. After several orbits of Io, at 42. 5 hours per orbit, the Earth is in K. Rømer reasoned that if light is not propagated instantaneously, the additional time it takes to reach K, that he reckoned about 3½ minutes, would explain the observed delay.

Picard collaborated and corresponded with many scientists, including Isaac Newton, Christiaan Huygens, Ole Rømer, Rasmus Bartholin, Johann Hudde, and even his main competitor, Giovanni Cassini, although Cassini was often less than willing to return the gesture.

The Danish and German geographical mile ( geografisk mil and geographische Meile or geographische Landmeile, respectively ) is 4 minutes of arc, and was defined as approximately 7421. 5 metres by the astronomer Ole Rømer of Denmark.

An early experiment to measure the speed of light was conducted by Ole Rømer, a Danish physicist, in 1676.

Ole Christensen Rømer (; 25 September 1644, Århus – 19 September 1710, Copenhagen ) was a Danish astronomer who in 1676 made the first quantitative measurements of the speed of light.

Christen Pedersen had taken to using the name Rømer, which means that he was from the Danish island of Rømø, to distinguish himself from a couple of other people named Christen Pedersen.

The brilliant contributions to atomic physics of Niels Bohr ( 1885 – 1962 ), the contributions to linguistics by Otto Jespersen ( 1860 – 1943 ), Ludwig A. Colding's ( 1815 – 1888 ) neglected articulation of the principle of conservation of energy, the pioneering work in anatomy and geology by Nicolas Steno ( 1638 – 1686 ), and the astronomical discoveries of Tycho Brahe ( 1546 – 1601 ) and Ole Rømer ( 1644-1710 ) indicate the range of Danish scientific achievement.

* Danish astronomer Ole Rømer measures the speed of light by observing the eclipses of Jupiter's moons, obtaining a speed of 140, 000 miles per second ( approximately 25 % too slow ).

Rømer is a temperature scale named after the Danish astronomer Ole Christensen Rømer, who proposed it in 1701.

During that time, Fahrenheit met or was in contact with Ole Rømer, Christian Wolff, and Gottfried Leibniz.

According to a letter Fahrenheit wrote to his friend Herman Boerhaave, his scale was built on the work of Ole Rømer, whom he had met earlier.

Using a telescope, Rømer observed the motions of Jupiter and one of its moons, Io.

If Rømer had known the diameter of the Earth's orbit, he would have calculated a speed of 227, 000, 000 m / s.

Rømer was born on 25 September 1644 in Århus to a merchant and skipper, Christen Pedersen, and Anna Olufsdatter Storm, daughter of an alderman.

There are few sources on Ole Rømer until his immatriculation in 1662 at the University of Copenhagen, at which his mentor was Rasmus Bartholin who published his discovery of the double refraction of a light ray by Iceland spar ( calcite ) in 1668, while Rømer was living in his home.

Rømer was given every opportunity to learn mathematics and astronomy using Tycho Brahe's astronomical observations, as Bartholin had been given the task of preparing them for publication.

In 1681, Rømer returned to Denmark and was appointed professor of astronomy at the University of Copenhagen, and the same year he married Anne Marie Bartholin, the daughter of Rasmus Bartholin.

In 1700, Rømer managed to get the king to introduce the Gregorian calendar in Denmark-Norway — something Tycho Brahe had argued for in vain a hundred years earlier.

Fahrenheit visited him in 1708 and improved on the Rømer scale, the result being the familiar Fahrenheit temperature scale still in use today in a few countries.

In 1705, Rømer was made the second Chief of the Copenhagen Police, a position he kept until his death in 1710.

In Copenhagen, Rømer made rules for building new houses, got the city's water supply and sewers back in order, ensured that the city's fire department got new and better equipment, and was the moving force behind the planning and making of new pavement in the streets and on the city squares.

After studies in Copenhagen, Rømer joined the observatory of Uraniborg on the island of Hven, near Copenhagen, in 1671.

In 1672 Rømer went to Paris and continued observing the satellites of Jupiter as Cassini's assistant.

Rømer added his own observations to Cassini's and observed that times between eclipses ( particularly those of Io ) got shorter as Earth approached Jupiter, and longer as Earth moved farther away.

We also continued to run a series of ads featuring endorsement of Rhode Island by industrialists who had recently established new plants here.

There is a marked tendency for religions, once firmly established, to resist change, not only in their own doctrines and policies and practices, but also in secular affairs having religious relevance.

Planes defined as parallel to the surface also cut through it into real space, and a depth is suggested optically which is greater than that established pictorially.

The non-identity of serum and red blood cell arylesterase was also established.

The statement also points to a classic paradox: The more men turn toward God, who is not only in himself the paradigm of all unity but also the only ground on which human unity can ultimately be established, the more men splinter into groups and set themselves apart from one another.

His name also survives in modern-day companies such as Dynamit Nobel and Akzo Nobel, which are descendants of the companies Nobel himself established.

Ann Arbor's Jewish community also grew after the turn of the 20th century, and its first and oldest synagogue, Beth Israel Congregation, was established in 1916.

The four dioceses of Wales were formerly also under the Province of Canterbury until 1920 when they were transferred from the established Church of England to the disestablished Church in Wales.

This established the existence of the phenomenon of aberration beyond all doubt, and also allowed Bradley to formulate a set of rules that would allow the calculation of the effect on any given star at a specified date.

It was during these early shows that Grant also established one of her concert trademarks: performing barefoot.

After several false starts during the 16th and 17th centuries the brass industry was also established in England taking advantage of abundant supplies of cheap copper smelted in the new coal fired reverberatory furnace.

Using a small Department of Defense International Military Education and Training ( IMET ) budget, the U. S.
